SPECFICATIEON forming part of Letters Patent NO. 358,659, dated Iiaich l, 185.7.

Application filed December 20, 1886. Serial No. 222,100. (No model.)

To all whom t may concern.-

Be it known that I, MAHLON HAMLIN, a citizen ol' the United States, residing` at Catawissa, in the county of Columbia and State of Pennsylvania, have invented certain new and useful Improvements in AxleeBoxes, of which the following is a specilication, reference being had therein to the accompanying drawings.

This invention relates to certain improvements in journal-boxes for that class of cars commonly employed in mines, in which there is necessarily a very limited amount of room for running and operating the ears; and it has for its object to provide for the ready and cony Venient removal of the car from the axles, when necessary to do so in case of a breakdown or other injury, so as to permit the car to be re paired and put into operation with the least possible delay, thus avoiding the obstruction to the track which would otherwise occur.

In the drawings, Figure l represents a side elevation of a portion of a miningcar, showingmy improvements applied thereto; Fig. 2, a transverse vertical sectional view of a journal-box and bearing constructd according to my invention. Fig. 3 represents a longitudinal view of the iournalbox, showing a portion of the axle; and Fig. 4, a bottom View of the journal-box.

The letter A indicates the truck or lower portion of the car, which is constructed in the usual manner.

B indicates the upper part of the box, which is flat on top, so as to rest iirmly against the bottom of the truck or car, to which it is secured by means of the usual bolts, C. The said part B of the box is provided with downwardly-extending sides b, which are provided with longitudinal rounded grooves c, for the reception of the rounded beads d of the lower portion, D, of the box, by which said portion is held in place.

The upper portion of the box is provided with a beveled recess, e, for the reception of a bcaring-blocl ,E, constructed ot'suitable metal, which is curved on its lower face to set over the axle, the block having beveled edges, by means of which it is conned in its seat.

The front ci' the upper portion, of the box is formed with a ange, F, having a socket, 5o g, for the reception ot' a pin, 11 by means of which the lower part ot' the box is confined to its seat. The said flange is rounded and beveled on its upper and lower edges, so as to form no sharp angles which would act as lines of breakage, and the downwardly-extending sides are similarly beveled for a like purpose, thus insuring the utmost strength to the box. The said sides are recessed below for the reception ot' the heads or screwnuts ot' the bolts, so that the same will not be exposed to injury.

The inner side of the lower portion of the box is provided with a semi-cylindrical opening, H, through which the journal of the axle passes, and by which it is held in place, and the recess for the bearing-block is provided with stops or abutments t', to prevent any longitudinal movement of the block.

As construct-ed, it will be perceived that the lower portion of the box, as well as the bearing-block, may be readily removed from their seats, so as to remove the axle or other parts for repair withoutinconvenience, which obviates the necessity of removing the bolts- 7 a tedious operation, and one which is difcult to perform.

The lower part ofthe box may be iilled with absorbent, to retain lubricating :material and distribute it to the axle.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. The combination, in an axle or journal box, of the upper portion having curved lon- 85 gitudiual grooves and the lower portion having correspondingly-shaped flanges or beads adapted to fit into said grooves to hold the parts together, substantially as specified.

2. In an axlebox, the combination, with the upper portion, B, provided with beveled recess e and'downwardlyextending sides, which have longitudinal grooves c on their inner faces, of thelower portion, D, provided with longitudinal ianges d, adapted to fit the 95 grooves c, and the bearingbloch E, adapted to lit the recess e, substantially as described.

3.
